We can modify the the `Cards_Fields` model to contain a foreign key to the image in the repository. This will create the proper linkage. For example:

```python
class Cards_Fields(models.Model):
    card = models.ForeignKey(Card)
    field = models.ForeignKey(Field)
    text_value = models.CharField(max_length=500)
    img_value = models.ForeignKey(Image_Field)
```
